Rear end rebuild

[96MustangGT]

Alright well since my rear end is going out im going to have to get it rebuilt. I believe the 96 cobra has a 28 spline rear? Was thinking about going to a 31 but besides the differential, 373 gears, and axles.. what else is needed? Sorry to sound ignorant but when it comes to something like this i can get a bit clueless even though ive read..... and if you think i should go another route let me know. Trying to spend the least amount of money by the way. (I know this is expensive)

Thanks

Bearing kit ,friction modifier, a bunch of tools , what kind of powert are you making

No need for 31 spline unless you are doing any reasonable amount of racing and making good power. Most of the time 28 spline will out last anything that 99 percent of the world will throw at it.

Right now im pretty much stock except for a bit of suspension work and some basic bolt ons but as soon as this gets fixed im planning on putting all bolt ons, 315s, and eventually a turbo (Two years from now or sooner). I figured i would go that route since i was in the need of redoing it already but if you guys think the 28 will be sufficient then ill do that.

 

[97stanger]

agreed, I think 28 will be MORE than enough for what you are running. Also like said, all you will need is differential, axles, gears, bearing kit, fluid, girdle gasket and tools and that should about wrap it up.

 

[96MustangGT]

Awesome really appreciate your guys help! Always admired your car there 97Stanger. VERYYYYY similar to what im looking for!! (Exterior wise)
By the way there isnt any website you guys know of that sales a package deal or something instead of buying almost everything individually? Ive looked but dont run into all in one

 

[97stanger]

any suggestions? This isnt including labor because i dont have the time to just attemp it myself besides bolt ons and i dont want to wait 1 year to start to complete a simple project lol

 

[vermilion]

go with 31 spline differential and 31 axles. thats my only recommendations.

 

[97stanger]

looks like youre all set to me. Like jason said you could always go with 31's, but honestly on a mild setup like yours if its saving you some coin than I would just stay 28 unless you had big plans in the future

 

[96MustangGT]

Oh ya i have big plans for it which is why i considered the 31. I think within a year itll hopefully be in the high 400s? Well see tho lol

 

[Raffaelli]

31's man. Only a couple hundred more on the diff and axles. But will survive much more power.

Oh and you forgot the full bearing/seal kit. Its about 70 IIRC.

 

[96MustangGT]

See now im lost lol. I thought the bearing and seal kit was this http://www.latemodelrestoration.com/item/LRS-4209FRB-K/Mustang-88-373-Ratio-Rear-End-Gear-Kit and wth is a 70 IIRC. lol sorry but this is why im here

 

[97stanger]

well in that case definitely go with 31's, dont want to have to do work twice

 

[96MustangGT]

Right i should have been more specific. But ya eventually i want to get it pushing quite a bit! Thats also exactly why i thought 31... for the future so i dont have to do it twice but from seeing your car im all for whatever u say lol you know more than i do. Ill post pics here soon and start a build thread

Even if you stick to your plans and are making 400 in the near future you still won't need 31 spline axles unless you plan on doing a good amount of track duty on DR's or slicks. Your not going to break an axle just driving down the street. Even at the track with street tires on you would just spin before you ever got the tractionto break a 28 spline axle.

I have a friend with a 500hp turbo fox an he runs stock axles, no track duty and he has been fine for years. If your doing extensive track time with good tiresthen yes get 31's if your going to drive it on the street then 28's are fine

 

[96MustangGT]

Well eventually i do want to take it on the track and have DR's. Also how hard is it to rebuild a rear end yourself and about how long would it take non stop to do? lol (Getting ideas) never done one or any hardcore mechanical stuff. Do have a general idea and know how to put things back the way they were. But cant say i can do a rearend just because i know that
